摘　　要：在真空滤油机研发过程中,对其真空获得设备前置涡旋真空泵的研究是一个重要的方面。涡旋真空泵在运行过程中,动、静涡旋盘之间间隙的存在导致了气体泄漏损耗,该因素会影响涡旋真空泵的极限真空度及其工作性能。分析了涡旋真空泵的径向泄漏及切向泄漏,计算了泄漏消耗的功率,说明了密封条原理和特点,提出了径向间隙和轴向间隙的密封措施,对提高涡旋真空泵抽速、改善其机构性能方面具有重要理论意义和工程实用价值,涡旋真空泵将在油处理行业得到进一步推广应用。The research of backing scroll vacuum pump is an important aspect of the development of vacuum oil-filter. The existing clearance between two scroll disks causes the leakage loss when scroll vacuum pump is working, which will affect its ultimate vacuum and working performance. Analyze the radial and tangential leakage of scroll vacuum pump, then the power consumption of leakage was calculated. The principle and characteristics of sealing strips introduced, and some sealing measures were put forward, which has very important theoretical significance and practical value to improve the pumping speed and working performance of scroll vacuum pump. The scroll vacuum pump will be popularized in the waste oil treatment industry in the future.
